That's 3 of us now, in our little group (or is it 4?). It further supports my belief that every single 360 without correction to the original design will fail completely and prematurely--not 33%, 100%.
I'm sorry about that, man. MS seems to have the process down to a science. Call support, have them set up a repair order under warranty. (All 360s are still under RRoD warranty.) They'll send you a "coffin", an empty box with packing material, sealing tape, and a return UPS label. Remove absolutely everything from the 360--HDD, memory cards, power supply, and of course the game disc. Send only the bare console.
It took less than 3 weeks for the whole process with me. The box got here quickly, and I shipped it the same day. I got a replacement back, which is both good and bad. The good is that the DVD drive is much quieter and better behaved. The old one was starting to have problems and make a racket on some games. Also, it's likely that at least the cooling system has been improved (or so I hope). The bad is that now I need to be tethered to mama Microsoft in order to play XBLA games I've bought. Those must be "dongled" either by the original console, or the XBL service. I think there's a way now to transfer licenses, but dealing with support about it was a waste of time during the one call I made, and I've been too lazy to try again.
